Definitions

  • the invention is related to a lifting gear and a specially designed container (retractable wheelie-bin).
  • the Chinese patent 200620097663.0 reveals a sinkable hydraulic dustbin. It consists of dustbin case, scissor linkage mechanism, hydraulic system, electrical controlling system and underground pit. At the front of the side case, there are front door shutter bold and opening lever, at the back there is a pushing board with a hydraulic pump, a photosensor is near the rubbish entrance on top and it is connected with PLC of the electronic control system.
  • One end of the scissor linkage mechanism is fixed on one side of the underground pit, the other end glides along a groove; a hydraulic pump is fixed within the scissor linkage mechanism on the bottom of the pit.
  • One end on the top of the scissor linkage mechanism is fixed on the side of the dustbin case and the other end also glides along a groove.
  • Chinese Patent 200410046941.5 reveals a balancing underground rubbish storage station which consists of dustbin case, hydraulic pumps, pulling cables, a set of pulleys and balancers.
  • the hydraulic pumps are installed under the dustbin case; one end of the pulling cables is connected with the dustbin case, the other with balancers, it bypasses a set of pulleys, which are fixed on the ground.
  • Cigar Patent 02274879.2 reveals a sinkable dustbin, which has a top hung door on the top of the case for throwing in rubbish; there is a bottomless drawer within the outer rubbish case, a pushing board at the back inside the case, with a scissors linkage mechanism operated by a hydraulic pump for compressing or pushing out rubbish.
  • the dustbin is sunk inside the ground with a hydraulic pump lifting system underneath to control its up and down.
  • Cigar Patent 200920008428.5 reveals a sinkable dustbin with pedal operating lid. Its lid is hinged to the top part of the outer case; there is a linkage bar within the outer and inner dustbin case, one end of which connects to the lid and the other to a pedal in the front. The lid will open when pressing the pedal.
  • the device can use a series incoherent and light action to accumulate energy to raise the loads when it is needed, and provide a whole set of solutions for underground storage, and achieve the goal of lifting loading without electrical or hydraulic power sources.
  • a retractable dustbin When using the device for disguising dustbins, it gives a special design, namely, a retractable dustbin.
  • This retractable dustbin idea comes from the fact that rubbish is usually accumulated daily; the extendable dustbin body can be adjusted according to the capacity need, and the dustbin can be partly or wholly buried underground, thus achieve the purpose of transfiguring the city environment but also reducing dig-depth of the device.
  • the device can be used for creating storage space, fulfill the needs of storing sundries, DIY or gardening tool, setting up a receiving box for internet shopping, etc. For this reason, we call the dustbin on the base board as loading, contents etc. in this description, in order that the design can be used for varied household storage purposes.
  • this device provides a lifting gear, which includes:
  • the device is classified into 3 standalone but also associated systems which can be used on its own or combined optionally, detailed as below:
  • FIG. 1 As it is an isometric drawing, there are some places which are not clear due to overlapping, please refer plan, and section drawings in FIG. 2-4 .)
  • this system provides a mechanism to accumulate energy for pulling up loading. Due to the fact that the system is connected direct to the baseboard, it is the main skeleton of the whole design (so when we use other system(s) mentioned below without this system, the basic structure still needs to be retained for passing on actions to lift up baseboard.)
  • the 1 st- balancer which is a certain shaped weight preferably use high density material such as iron or lead etc. with a cuboid shape in order to reduce the volume of the device; the function of it is to cancel out part or all of the loading weight.
  • the 1 st balancer's descending causes the baseboard's ascending.
  • the baseboard can be separated with the container above or can be combined the bottom of the container with the baseboard and chains/ropes can be fixed to the bottom of the container (refer to the Example Application 2).
  • the 1 st direction-controlling ratchet (called 1 st -switch below), which is a controllable 2 direction ratchet wheel, is used to set the 1 st- Axle's allowing turning direction, which can be achieved with other existing technology.
  • FIG. 11 is one of the designs, its controlling button (which is formed by hard plastic in the core, moulded with soft rubber around it) is placed on top of the pedal of the 1 st applying gear of auxiliary lifting system; it pushes the toggle bar ( 27 ) in a place where it sets the turning in only one direction (shown by the arrow in the figure), therefore the ascending or descending state can be achieved by pressing buttons.
  • Another system of the device includes: a 2 nd -Axle ( 14 ), a pair of 2 nd -fixed-pulleys ( 12 ); a 2 nd -balancer ( 10 ) which is hung under the 1 st -balancer by a pair of 2 nd -chains ( 11 ) through holes ( 24 ) in the 1 st -balancer (a pair of plummets are on the other end of the 2 nd -chains), it also includes a clutch device ( 21 ) which can clamp onto the 1 st -balancer when it touches its bottom.
  • a 2 nd stepping gear for pulling up the 2 nd -balancer which includes: a 2 nd -press-lever ( 20 ) (or surface) connected with the top lid, a gliding bar underneath, a large driving wheel ( 17 ), a small driving wheel ( 16 ) on the same driving axle ( 25 ), a driven wheel ( 15 ) on the 2 nd axle and a direction-controlling ratchet ( 18 ) (called 2 nd -switch below, is the same type as the 1 st -switch) on the driving axle ( 25 ).
  • Other methods of lifting the 2 nd -balancer can be used.
  • This system is an auxiliary to complement the 1 st balancer system.
  • the 2 nd -balancer's lifting is designed to use one-hand operation to accumulate energy of position by unaware daily operating.
  • the 2 nd -balancer ascends and touches the bottom of the 1 st -balancer, its clutch clamps and hangs on to the 1 st -balancer, thus the total weight is used to lift the loading on the baseboard through the 1 st balancer system.
  • Its material and shape selection follows the same requirement of the 1 st -balancer.
  • the reduced ratio of the operating force to the 2 nd -balancer is in the reverse ratio of raising distance of the 2 nd balancer, that is to say, the more operating force reduced, the less distance the 2 nd -balancer raised up, and more times of operating is needed. Because the weight of 2 nd -balancer is set according to the potential weight of load, so the ratio of the large and small driving wheel diameters, ratio of the arm length of the force points, total lifting height and designated pressing times need to be calculated accordingly.
  • the 2 nd -switch is the same as the 1 st -switch, for example, is a 2-way controlling ratchet (refer to FIG. 6 ), is used to set the allowing turning direction of 2 nd -axle. For example, when the 2 nd balancer is going up, the 2 nd -axle is only allowed turning in counter clockwise (view from right to left); and vice versa.
  • the large driving wheel When the large driving wheel is working, it is toothed with the 2 nd -gliding-bar, so when the gliding bar goes up or down, the large driving wheel will turn in both directions.
  • the large driving wheel is a one-direction ratchet wheel, it will slip around the driving axle when gliding bar goes up, but when gliding bar goes down, it drives the large driving wheel turning in counter clockwise (view from left to right; and the 2 nd -switch must be toggled to the position to let the driving axle turn in counter clockwise at this moment), the small driving wheel will be force to turn in the same direction around the driving axle ( 25 ), and then the small driving wheel will drive the driven wheel ( 15 ) and its axle ( 14 ) to turn in clockwise thus life up the 2 nd balancer to a certain height.
  • 5C is showing the tip of 2 nd -gliding-bar detailed design in which it can sit on opening lip on the top of the device, and the action to push it in the sitting slot of 2 nd -gliding-bar ( 31 ) will also make sure pulling the toggle bar to the correct position of the 2 nd -switch by the linkage sleeve ( 28 ), simplify the operation when opening the top lid to raise the loading.
  • the function of the clutch in the 2 nd -balancer is to connect 2 balancers when they ascend and touch each other, and the 2 nd -balancer's weight will be added on to the 1 st -balancer in order to raise heavier loadings.
  • the requirement for designing the clutch is firstly, to set it in an inactive mode when the 2 nd -balancer is on the bottom of the device, therefore when operate the 1 st -balancer System to store up some energy by pushing down the baseboard, only the 1 st balancer is lifted up.
  • FIG. 7 ( 1 - 4 ) is the illustration of the working states of the clutch;
  • FIG. 8-9 are 2 designs of the clutch, they are all use balancer's own weight to push a scissor-shaped clamper or spring bolts in a separated position with the 1 st -balancer's groove or lugs, and are in working state when leaving the bottom position under the effect of springs inside.
  • this system can be applied to assist its lifting by providing extra force through the foot-pedal; other situations that this system need to be used are that when the 2 nd -balancer system is out of order or the 1 st -balancer's weight cannot outdo the loading, or when this system is chosen as the only lifting method due to the cost consideration.
  • This system includes a pressure surface ( 6 , the pedal), a 1 st -gliding-bar ( 7 ) underneath and a 1 st -driven-ratchet-wheel ( 8 , fly wheel).
  • the fly wheel ( 8 ) is connect with the 1 st -axle ( 3 ).
  • This 1 st -force drives the fly wheel ( 8 ) to turn the 1 st -axle and lifts up the baseboard.
  • the gliding bar Before the pedal is pulled up for its operation, the gliding bar is in a separated position with the fly wheel, therefore, it will not obstruct the operation of the base board's ascending or descending; when pressing button (refer to FIG. 10 .
  • Component 35 its core is hard plastic with elastic soft rubber surrounding) at the front edge of the pedal, to let the fixing bolt ( 36 , spring 39 fixed within) release the pedal ( 6 ). While lifting the front of the pedal, the spring ( 38 ) underneath pulls the pedal forward, the back edge ( 33 ) of the pedal slips into the turning groove ( 34 ), and the gliding bar snaps in with the fly wheel ( 8 ) ( 37 is a stopping bar).
  • the 1 st -switch ( 9 ) (which is a 2-way controllable ratchet) is set in the position of allowing the 1 st -axle turning in counter clockwise, but not clockwise.
  • ‘ascending’ button needs to be pressed (refer to FIG. 11 ) to let the loadings on baseboard be pulled up step by step by each footwork without slipping backwards.
  • the device is placed within a double layer case (considering the requirement of anticorrosion and cost, plastic is preferred), namely, the outer case (contacted with earth) and the inner case which is for the container or contents of the base board moving within, and the double layer walls of the case also support the parts of the device.
  • the container or content on the base board can be designated for different type of usage, such as a cupboard or shelves for storing sundries and tools, a container for carrying solid/liquid or a dustbin.
  • This retractable wheelie bin consists of 2 similar height sections, the upper barrel ( 40 ) is wider, the lower barrel ( 41 ) is narrower.
  • FIG. 12 shows front, back, side and retracted front views of the retractable wheelie bin. When it is extended, it is a standard height wheelie bin for standard dustbin truck to handle; comparing to usual standard wheelie bin, the distance of the 2 wheels ( 45 ) on the base is shorter, making it goes into the lower barrel body, in order that they would not obstruct the upper barrel coming down when it is retracted.
  • the rubber ring ( 47 ) on the lower barrel edge will be squeezed and hold the upper barrel edge (refer to FIG. 15 ), then pull the small pivoted lever ( 44 ) positioned diagonally near the touching edges of 2 barrels to secure it ( FIG. 14 ); when retracting it, process the above steps in a reverse order.
  • the idea of the retracting device comes from the fact that the quantity of rubbish accumulated is increased day by day, its usage can match the adjustable volume, and can be hidden partly or wholly underground in order to transfigure the street view with less digging depth of the device. More specifically, after each dustbin collection, a user retracts the bin, press down into an underground device with half of the normal dustbin height. Afterwards, by lifting and closing the top-lid of device (there is a connecting bolt ( 46 ) to hold the wheelie bin lid which makes them open at the same time, refer FIG.
  • the device accumulates 2 nd -balancer's energy (be aware that due to the height is half the standard dustbin, the pressing time on the lid is also half of the standard bin);
  • 2 nd -balancer When there is not enough capacity for the rubbish, firstly watch out if the 2 nd -balancer is connected with the 1 st -balancer. If not, pressing the lid a few more times until they clamp together, then push the gliding bar to come off the large driving wheel (and the linkage sleeve also set the 2 nd -switch to the position to allow the 2 nd -balancer going downwards), and erect the lid in vertical position, and pull to extend the bin, its capacity will be doubled.
  • press the 1 st switch the dustbin will come up automatically. After the rubbish collection, repeat this process cycle.
  • the measurement of the top edge of the dustbin follows the standard wheelie bin, but is set as thin as possible in order to make the recess of the device top shallower for easy design of the 2 nd defense of waterproof.
  • the lid design besides the functionality, tries to break through its traditional appearance; its hinge ( 43 , FIG. 13 ) design considers waterproof and turning 270 requirement, as well as hand grabs ( 48 ) for the handling of the bin. Please refer to the Application Example 1 for more details.

  • FIG. 16 Connecting Bolt Design of Device's Top Lid and Retractable Bin Lid
  • This example presents a device to hide away the standard wheelie bin or retractable wheelie bin described earlier, to transfigure city streets and increase useable space of households.
  • the lifting device uses the 3 systems mentioned above.
  • the 1 st -balancer is a 30 kg cast iron block, which weighs up normal person's 20 kg+pressing force, plus 10 kg empty bin and base board's own weight, makes it easy to press into the ground.
  • the 2 nd -balancer is a 25 kg cast iron block, making the total balancers' weight 55 kg, which satisfies the requirement of normal household weekly rubbish weight's lifting need.
  • the top lid has to be set in 90° position.
  • the 2 nd balancer is not in the highest position connected with the 1 st -balancer, press a few more times to make them connect before setting the gliding bar resting on the open lip. Failing to do so will trigger the linkage sleeve ( 28 ) pulling the toggle bar of the 2 nd -switch and the 2 nd -balancer will sink into the bottom of the device, therefore the 2 nd -balancer loses its effect in this process cycle.
  • the pedal's design also considers combined operations to simplify the application.
  • Placing the ‘Ascend’ and ‘Descend’ buttons on the pedal is a simplified design which is also an advantage for water proof.
  • the total ratio of the moment from the pressing point to the 2 nd -balancer is the accumulation of these two applied moments, which is:
  • P1 pressing force
  • moving distance ratio is the reverse ratio of the forces
  • the lifting device can adopt any 1 or 2 of these 3 systems to suit different using habit or different budget requirements, details as below (these are also general characteristic portraits of different systems and combinations):
  • This example can be used as varied domestic sundries storage solutions. Because there is no regular opening/closing top lid movement, the 2 nd balancer system can be omitted, let use the cheapest low cost 1 st balancer system. Its balancer weight can be set with weight of potential item(s) storing, and considering operating pressing and lifting force, say 20 kg, therefore, the difference of the minimum and maximum nominal loadings is 40 kg. So, if storage for gardening or DIY tool is heavy, 80-120 kg nominal loads (including the container's weight) can be chosen, and 100 kg mid-value balancer weight can be set. Therefore, a user can easily press or lift 20 kg force to operate the storage device.
  • the cabinet As there is no need of pulling the cabinet away for this device, we combine the cabinet with the base board, set some shelves for sorting items; the top lid is also not needed and can be designed with the waterproof requirement. If it is for light objects, say, a sinkable receiving cabinet of internet grocery shopping, or a sinkable storage facilities for households with ground floor (such as a sinkable chest of drawers, etc.), 20 kg balancer is possibly enough, for this kind of application, this single 1 st balancer system like this would be very easily handled and flexible.
